Default Just brewed a beer with 308 IBUs, A little over the top?

I recently brewed a clone of Pliny the Elder with 172 IBUs and it was fantastic. Last week I tasted a beer with 260 IBUs and it was even better. So I decide to try a bigger ipa today. I came up to 308 ibus. Can't wait to taste the final result. I'll be using about 250g to dry hop it in 2 weeks, 200 g the first week and 50 the second week.

Patience is tough on me lately...

Mathmatically yes it's possible to get up there but I was under the impression that past about 120 it's not really absorbing anymore. That't a huge amount of hops... sounds fun

I think you are right but can't wait to taste it.
The wort was tasty.

That's just a waste of perfectly good hops.

As mentioned, 100-120-ish IBUs is the practical limit where hop utilization flattens out and you don't actually get any more bitterness.

+1 to Kombat...just a waste of perfectly good hops. The saturation limit for iso-alpha acids is well under 100 ppm (aka IBU's) and the OP should aim for 1001 IBU's to test the enjoyable grassiness that comes from the remaining drops of wort that make it out of that mass of hops. There won't be much, so treasure them. Hops aren't the only thing wasted by excessive hopping, wort is lost too.

Even though the OP was over saturation for alpha acids and bitterness, don't additional hop additions provide flavor, aroma, and mouthfeel? In other words, are there benefits besides IBU from massive hopping? Does a calculated 300+ IBU beer have a perceptible difference from one that's 200, regardless of IBUs measured in a lab?

Depends when the hops were added. If they were mostly added at the start most aroma and flavor would boil off.

Yes, there would. I was a bit harsh above. Although the saturation limit for iso-alpha acids would kick in, there are other bittering and flavor components that will alter the perception of bittering in a beer. They are limited and they may be less pleasant than typical bittering compounds, but they exist.

Ability of alpha acids to isomerize and reaching a saturation point is always quoted. I wonder though if other compounds contributed by hops increase which allows glycosides produced by yeast (not much by saccharomyces though) to act on the hops giving a complex flavor. Sure there is a saturation point for everything, but while hes wasting hops in an IBU sence, he may not be when concerning other compounds.
